There are two molecules in the asymmetric unit of the title compound, C19H22N2O. Both molecules have an E conformation about their C=N bonds and both piperdine rings adopt chair conformations with their N atoms adopting pyramidal geometries [bond angle sums = 329.8 (4) and 330.2 (4)°]. Both molecules feature an intramolecular O—H
N hydrogen bond, which generates an S(6) ring. The dihedral angles between the phenyl and benzene ring planes are 45.97 (18) and 66.0 (2)°. Short O—HO contacts occur in the crystal.

The title compound, C15H14FNO2, has an E conformation about the C=N bond, which facilitates the formation of an intramolecular O—HN hydrogen bond. The F atom is disordered over two adjacent sites in a 0.65 (7):0.35 (7) ratio. The dihedral angle between the benzene ring planes is 14.2 (2)°. In the crystal, molecules are linked by O—HO hydrogen bonds, forming C(14) [010] chains.
